Methods and Apparatuses for Location Area Update

Abstract

Disclosed are apparatuses and methods for location area update. An example method may include transmitting a first request to establish a radio link, the first request including information on a first location area update, transmitting a second request to execute the first location area update via the radio link, and releasing the radio link in response to at least one status of an access stratum feedback to the second request. Related apparatuses and computer readable medium are also disclosed.

1 . A method comprising:
 transmitting a first request to establish a radio link, the first request including information on a first location area update;   transmitting a second request to execute the first location area update via the radio link; and   releasing the radio link in response to at least one status of an access stratum feedback to the second request.   
     
     
         2 . The method of  claim 1  wherein the information indicates that a one-way update procedure from a mobile device is allowed. 
     
     
         3 . The method of  claim 1  further comprising:
 in response to the status of the access stratum feedback indicates receiving a negative acknowledgement or missing acknowledgement, initiating at least one second location area update including at least one feedback from a core network to a mobile device. 
 
     
     
         4 . The method of  claim 1  further comprising:
 initiating the first location area update in responding to an expiration of at least one timer; and 
 resetting the at least one timer in a case where the status of the access stratum feedback indicates receiving a positive acknowledgement. 
 
     
     
         5 . The method of  claim 1  further comprising:
 determining an enablement of the first location area update according to a message from a core network. 
 
     
     
         6 . The method of  claim 5  wherein the message further includes a maximum execution number of the first location area update for a mobile device. 
     
     
         7 . A method comprising:
 receiving a first request from a mobile device to establish a radio link, the first request including information on a location area update;   receiving a second request to execute the location area update via the radio link from the mobile device;   transmitting a third request to a core network, the third request being based on the second request and informing the location area update of the mobile device; and   releasing the radio link after transmitting an access stratum feedback to the second request via the radio link.   
     
     
         8 . The method of  claim 7  wherein the information indicates that a one-way update procedure from the mobile device is allowed. 
     
     
         9 . The method of  claim 7  further comprising:
 determining an identity associated with the mobile device in response to the first request being received, the third request being determined based on the second request and the identity. 
 
     
     
         10 . A method comprising:
 receiving information on a location area update regarding a mobile device from an access network; and   disabling a location area update feedback to the location area update regarding the mobile device.   
     
     
         11 . The method of  claim 10  wherein the information indicates that a one-way update procedure from the mobile device is allowed. 
     
     
         12 . The method of  claims 10  to  11  further comprising:
 initiating a location area deregistration for the mobile device in responding to an expiration of at least one timer; and 
 resetting the at least one timer in response to receiving the information on the first location area update regarding the mobile device. 
 
     
     
         13 . The method of  claim 10  further comprising:
 transmitting to the mobile device a message for enabling the first location area update to the mobile device before receiving the information on the first location area update regarding the mobile device. 
 
     
     
         14 . The method of  claim 13  wherein the message includes a maximum execution number of the first location area update for the mobile device. 
     
     
         15 . The method of  claim 10  further comprising:
 in response to a current location area of the mobile device being outside of a current location area list of the mobile device, paging the mobile device in at least one location area including the current location area after receiving the information on the first location area update regarding the mobile device. 
 
     
     
         16 . An apparatus comprising:
 at least one processor; and   at least one non-transitory memory including computer program code,   the at least one memory and the computer program code being configured to, with the at least one processor, cause the apparatus to:
 transmit a first request to establish a radio link, the first request including information on a first location area update; 
 transmit a second request to execute the first location area update via the radio link; and 
 release the radio link in response to at least one status of an access stratum feedback to the second request. 
   
     
     
         17 . An apparatus comprising:
 at least one processor; and   at least one non-transitory memory including computer program code,   the at least one memory and the computer program code being configured to, with the at least one processor, cause the apparatus to:
 receive a first request from a mobile device to establish a radio link, the first request including information on a location area update; 
 receive a second request to execute the location area update via the radio link from the mobile device; 
 transmit a third request to a core network, the third request being based on the second request and informing the location area update of the mobile device; and 
 release the radio link after transmitting an access stratum feedback to the second request via the radio link. 
   
     
     
         18 . An apparatus comprising:
 at least one processor; and   at least one non-transitory memory including computer program code,   the at least one memory and the computer program code being configured to, with the at least one processor, cause the apparatus to:
 receive information on a location area update regarding a mobile device from an access network; and 
 disable a location area update feedback to the location area update regarding the mobile device.
